[NTLK] Newton gateway idea

[Jake Bordens]

The WiReach module on my internal card does support WPA2 encryption.  It also has AT command for performing SSL encrypted transmissions.  If someone were so inclined, it could be used to write NewtonOS software for talking to encrypted mail servers and web servers.  It would be outside the NIE stack though.  You can also gain access to the AT command set by telnetting into the WiReach from an active PPP session, so there's that.  There's a lot of capability in that module, if someone were inclined to write NewtonScript code to use it.

The internal serial slot does support up to 2 megabits per second serial I/O if you use an external clock.  The timing diagrams are in the N2 platform documents.  I didn't want to add another microprocessor to my internal WiFi card and figure out how to bit-bang the external clock, but it is possible.

Using WiFi means the link would need to be insecure (since the Newton doesn’t support WPA2), and so I’d really like to avoid that.  Using Bluetooth would possibly work, with a Pico BT card in the Newton, but … I’m reluctant to require that dependency, especially given limited supplies of suitable BT cards.

One option I’ve considered is using a PCMCIA extender to attach to a “sleeve”: a slight bulge on the back of the Newton could support a circuit board, perhaps external connectivity (ie. USB), and perhaps even an extended battery).  But .. if it can be done internally, using the Newt’s power supply, I think it’d be the best option.

I’ve no knowledge of “maker”-class folding of metal parts, but .. maybe it’s possible to build a 3D printed (or CNC routed) plastic skeleton, populate it with wire connectors, and wrap it in the metal shell?  A limited run of SMT-compatible Interconnect plugs would open up a lot of possibilities.
